Yii2 save array of form fields to a single database field - php

Question

How can I save an array of fields in Yii2 the current/default setup only works for field which aren't array.
Below are the form fields I need to save into the single field:
<div class="repeat">
<table class="wrapper" width="100%">
<thead>
<tr>
<td width="10%" colspan="4"><span class="add">Add</span></td>
</tr>
</thead>
<tbody class="container">
<tr class="template row">
<td width="10%"><span class="move">Move</span></td>
<td width="10%">An Input Field</td>
<td width="70%">
<?= $form->field($model, 'field1ofarray[{{row-count-placeholder}}]')->textInput(['maxlength' => 255])->label('Field Label') ?>
<?= $form->field($model, 'fieldofarray[{{row-count-placeholder}}]')->textInput(['maxlength' => 255])->label('Som field') ?>
<?= $form->field($model, 'field3ofarray[{{row-count-placeholder}}]')->textInput(['maxlength' => 255])->label('Field Label') ?>
<?= $form->field($model, 'field4ofarray[{{row-count-placeholder}}]')->dropDownList(['instock' => 'Instock', 'soldout' => 'Sold Out', 'scheduled' => 'Scheduled']); ?>
</td>
<td width="10%"><span class="remove">Remove</span></td>
</tr>
</tbody>
</table>
Current Controller (I need to know how I can loop through array and save as well as saving other normal fields in my form):
public function actionCreate()
{
$model = new GrailWall();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}

In my case I didn't need to make any changes to the controller at all.
You can just make a field in your db record, something like 'config_json` and then define a virtual property with getter and setter in your model.
public function getConfig()
{
return json_decode($this->config_json);
}
public function setConfig($value)
{
$this->config_json = json_encode($value);
}
Also set your virtual property to be safe in the rules so Massive Assignment works.
public function rules()
{
return [
[['company_id', 'created_at', 'updated_at'], 'integer'],
[['class'], 'required'],
[['config_json'], 'string'],
[['class'], 'string', 'max' => 255],
[['config'], 'safe']
];
}
Now you can set inputs like this in your view
<?= $form->field($model, 'config[ga_id]', ['labelOptions' => ['label' => 'Google Analytics Tracking ID']])->textInput(['maxlength' => true]) ?>

Answer 2

you can use loadMultiple(), look at this
this is about tabular/multiple input.
Otherwise load the modal you need using load($_POST[your_form_name].

Answer 3

models
public function getNetworkTypeArray()
{
return explode(',', $this->network_type);
}
public function setNetworkTypeArray(array $value)
{
$this->network_type = implode(',', $value);
}
controller
public function actionUpdate($id)
{
$model = $this->findModel($id);
if ($model->load(Yii::$app->request->post())) {
$model->setNetworkTypeArray($model->network_type);
if ($model->save()) {
return $this->redirect(['index']);
}
}
$model->network_type = $model->getNetworkTypeArray();
return $this->render('update', [
'model' => $model,
]);
}

Answer 4

$form->field($form, 'email[]')->textInput(['id' => 'email-0']);
will render:
<input type="text" name="Form[email][]" id="email-0">
Please note double square brackets in ($form, 'email[]').
ID attribute must be set explicitly unique, otherwise duplicate IDs will render, which does not conform with W3C/javascript standards.

Answer 5

instead saving in array you can save in string, to that use tne variables as normal in the view, ex:
fieldofarray instead fieldofarray[],
and in the controller use the implode function, ex:
public function actionCreate()
{
$model = new someModel();
if ($model->load(Yii::$app->request->post())) {
$model->fieldofarray = implode (",",$model->fieldofarray);
$model->save();
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
